Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66996, here are decompositions:

  • 19 + 66977 = 66996
  • 23 + 66973 = 66996
  • 37 + 66959 = 66996
  • 47 + 66949 = 66996
  • 53 + 66943 = 66996
  • 73 + 66923 = 66996
  • 107 + 66889 = 66996
  • 113 + 66883 = 66996

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66996 first appears in π at position 110,893 of the decimal expansion (the 110,893ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
